Security

The MD4 and MD5 algorithms are currently considered weak for cryptographic use.
The algorithms should be used only for compatibility with legacy systems or
protocols.

The SHA1 algorithm is also believed to have some weaknesses. Migration to
one of the SHA2 algorithms–including SHA256, SHA386 or SHA512–is highly recommended when
compatibility with data formats and on wire protocols is permitted.
